you modify nothing. sweet eh? just think og mpls as one big pvt vlan. you're
using teh SP's network but it's YOUR pvt network, isolated from everyone
else. of course you can route traffic from this vlan out to internet routers
if you wish.
the SP will give you the WAN link addresses and you'll need to configure
your gear with those. ...but you don't need to change your LAN networks at
all. the ISP will accept and advertize whatever IP blocks you give them,
public or private doesn't matter. It's an *isolated* network, never hits the
"internet at large", so there's nothing to change.
one suggestion......if you want all your locations to access the internet
from one central site (your head office location for example)....make sure
you get a fat pipe at that location and inject a default route via BGP....
for a diagram....think of a FR cloud with several spoke sites...that's
pretty much it. if one site goes down, all the other sites are still
reachable via the cloud (eliminates the need for traditional point-to-point
links between each location).
